The absolute fluxes of C₂H₂ (top) and H₂O (bottom) as a function of the strength of the 10 µm silicate feature (left), stellar accretion rate (middle), and dust disk mass (right). The fluxes are normalized to a distance of 120 pc. Upper limits (downward triangles) are the 3σ fluxes; objects with M_dust upper limits are either leftward facing triangles if the molecular species is detected, or rotated triangular markers if both the flux and dust mass are upper limits. Error bars are smaller than the points for most targets. The blue points are the T Tauri sample and the red points are the VLMS targets. The PCCs and p-values can be found for each panel. Significant correlations (p-value<0.05) are provided in bold.
